Programming NSE Python API

symbol = "NIFTY"

start_date = "15-05-2023"

end_date ="1-06-2023"

instrumentType = "options"

expiry_date ="15-Jun-2023"

strikePrice = 18600

optionType="PE"

print(derivative_history(symbol,start_date,end_date,instrumentType,expiry_date,strikePrice,optionType))

Above code is giving an error. The error:

raceback (most recent call last):

Try the example as shown here NSEPy Functions - Unofficed and see if it it showing same error. And share.

Another way is to shift to nsepython’s server version which you can find here - [Update] NSEPython not working in AWS, Google Cloud and WebServers - #24 by dexter

Let me know if you face problem

append has been depreciated in Python’s latest version, it can be replaced by concatenate.

Already fixed. Upgrade the version of NSEPython

After Upgrade almost every thing which is using NSEpython is throwing error
